Assessing ochric soil profiles using magnetic susceptibility measurements

Ochric soils are characterized by thin, light-colored surface horizons with low organic matter and nutrient content, commonly found in arid and semi-arid regions. These soils exhibit limited water and nutrient retention and are prone to erosion, making them challenging for agricultural use without significant management. However, their clear stratification and minimal organic interference make ochric soils a valuable subject for studying soil processes and their development.

Magnetic susceptibility is an efficient, non-destructive tool that complements traditional soil analysis methods, enhancing our understanding of the processes shaping soil stratification and development, reflecting the concentration and type of magnetic minerals, such as magnetite or hematite. It serves as a reliable proxy for studying soil genesis, mineral composition, and pedogenic processes.

The vertical distribution of magnetic susceptibility in soil profiles provides valuable insights into processes like mineral weathering, sediment deposition, and soil horizon development. It also helps detect environmental changes, such as shifts in vegetation or climate, and anthropogenic impacts, including land use changes or pollution.

This study focuses on measuring magnetic susceptibility in ochric soil profiles to assess its variability at different depths. The findings contribute to advancing soil classification methodologies and improving environmental monitoring and land management.
